1. If you don’t bring dumpling bowls at the beginning of winter, your ears will freeze off and no one will care. The original name of dumplings is said to be "Jiao Er", which was first invented by Zhang Zhongjing, a Chinese medical sage. The story of his "Quhan Jiao Er Soup" is still circulated among the people of our country. According to legend, at the end of the Eastern Han Dynasty, "Medical Sage" Zhang Zhongjing served as the prefect of Changsha, but later resigned and returned to his hometown. Just in time for the winter solstice, he saw that the people in Nanyang were suffering from hunger and cold, and their ears were frostbitten. At that time, typhoid fever was prevalent and many people died of the disease, so Zhang Zhongjing summarized the clinical practice of more than 300 years in the Han Dynasty, built a medical shed locally, set up a large pot, simmered mutton, chili peppers and medicinal materials to dispel cold and improve heat, and wrapped them in dough. It is shaped like an ear and is given to the poor with soup and food after cooking. The common people ate it from the winter solstice to New Year's Eve, resisting typhoid fever and curing their frozen ears. From then on, the people in the village and later generations imitated the production and called it "dumplings" or "dumplings". In some places, they were also called "Bianshi" or "hot noodle dumplings". Since then, the custom of eating dumplings during the Winter Solstice has been passed down. Firstly, it is to commemorate this great and famous doctor. Secondly, isn’t there an old saying, “You are what you eat to make up for it.” The Beginning of Winter means the arrival of winter. When the weather gets cold in winter, ears exposed to the outside can easily get frostbite. Therefore, eating some dumplings that look like ears and patching up the ears is the most considerate way for family members to care for their loved ones.

2. The time of Jiaozi. "Jiao" means alternation, handover, and exchange. New Year's Eve is the transition between the old year and the new year, and the Beginning of Winter is the transition between autumn and winter. Therefore, you must eat dumplings during the "crossing" period.
